It was a terrifying afternoon Tuesday for two young girls home alone in Cary. Police say a man kicked down the back door of their home in the 700 block of Castalia Drive while the girls were inside. They ran to a bedroom and quickly called 911.

In that call you can hear just how scared the girls were but also how calm they were in giving the 911 operator all the information she needed.

911 call: "Someone is trying to break into my house."

That's how the several minutes long 911 call began when those two girls, ages 11 and 14, called for help after two intruders broke into their home.

"They were in the dinette and when they saw the door being kicked in, they ran back to their bedroom and closed the door," said their grandfather, Dave Trantham.

Trantham arrived at the home shortly after police did to find the two safe and sound thanks to their own quick thinking.

"They did exactly the best thing they could have done," said Trantham.

Cary Police tell ABC11 that the two ran to a bedroom and hid under a desk to call 911 around 3 p.m.

Operator: "So the door's been kicked in they are inside the home?"

Caller: "Yes."

Operator: "Stay on the line with me don't say anything unless absolutely necessary. Police are on the way OK."

"Two black males came to the front door, knocked, left without the girls answering the door, approximately 15 minutes later, someone starting kicking in the back door," said Cary Police Lt. Joe Clifton.

Clifton said the two suspects were apparently surprised and scared off when they found the two girls hiding in a bedroom.

"The suspects saw them. They left," said Clifton.

He says the suspects drove away in a white Ford Flex with a black top.

It's not yet clear what the two were after or what they were able to get away with. However, it is clear that they didn't stay long thanks to the girls calling for help and the information they were able to give police.
